HORSE HAY-RAKE.

SPECIFICATION forming part ,of Letters Patent No. 233,191, dated October 19, 1880,

Application filed April 20, 1880.

To all whom it may concern:

Be it known that I, WILLIAM S. BATES, of Cincinnati, in Hamilton county, Ohio, have invented certain Improvements in Horse Hay- Rakes, of which the following is a specification.

This invention relates to horse hay-rakes of the class that are dumped by the power of the .team by means of a ratchet-wheel attached to and revolving with each ground-wheel, and

operating on a device attached to the rakehead.

It consists in such a construction and arrangement of. parts that the ratchet-wheels are brought near the center of the rake by means of two shafts constituting vertical prolongations of the hubs of the ground-wheels, and the force is applied to the rake-head near its center instead of at its ends, and in certain other devices and combinations, all of which Will be more particularly specified in the claims at the end hereof.

1n the drawings, Figure 1 is a front View of one of my rakes with the body removed and 2 5 the lifting-bar depressed, the position of the thills and middle beam and the bearings of the ground and ratchet wheel shafts being indicated by dotted lines. Fig. 2 is a partly sectional side view. Fig. 3 is the lifting-bar 0 and its immediate connections; and Fig. 4 is a plan of the frame or body, the position of the ratchet-wheel shafts and their bearings being indicated by dotted lines.

A A are the thills, having near their ends 3 5 the bearin gs a a. B, C, and D are cross-beams of the frame. The beam D is behind the ratchet-wheels, and, serves as a support for the cleaner-rods cl.

E is the middle beam of the frame, extend- 4o ing from C to D, between the two ratchet- Wheels, and having the bearingefor the inner ends of the ratchet-wheel shafts. F is the rake-head, supported by suitable bearing-arms ff from the ratchet-Wheel shafts, so as to re- 5 volve about the same. G is the tooth-board, supported by backward extensions of the arms ff. 9 are the rake-teeth. H is the shaft connecting the ratchet-wheel I with the groundwheel J. H is the shaft connecting the ratch et- Wheel I with the ground-wheel J. These shafts have their bearings at a a and c, and

(No model.)

are secured each to its respective groundwheel, so as to be revolved thereby.

I I are the ratchet-wheels, secured, respect ively, to the shafts H H, so as to revolve therewith. i i are hubs on the ratchet-wheels, which abut against the middle bearing, 6, and centralize the rake-body, and against the inner rake-head bearings,ff, and centralize the V rake-head. It is thus unnecessary for the outer bearings of either the rake head or body to abut against the ground-wheels.

K is the lifting-bar. It is a plain bar resting on the arm M, and having a cylindrical tongue, k, at each end for attachment of the spring-rods L, which attach it to the rake-head. The springs L L may be formed of a single piece of steel bent at l l, and bent into a loop or eye, Z, at each end. They may be attached to the lifting-bar K by passing the tongue it through the loop or eye I, and then slipping on a washer, 7c, and hammering the ends of the tongues. The portion 1 l constitutes a rock-shaft, and rests in the books it 011 the rake-head. The two side portions, L L, extend forward outside the ratchet-wheelsthat is, with both ratchet-wheels between themso that in dumping, whether from one Wheel or both wheels, they are always strained in tension.

M is an arm attached to the rocking-bar l I, so that the latter may be rocked by it, and extending forward under the lifting bar, the front end being turned up for connection of the toggle 0 0. M is a downwardly-projecting arm, also attached to the rock-bar Z l. m is a spring connecting the arm M with the bearing 0, and serving to counteract the weight of the lifting-bar, 850., and keep it out of gear With the ratchet-wheels. It also, in connection with the toggle, prevents the lifting-bar being thrown out of gear before the proper time after it has been thrown in. m is a screw and nut for adjusting the tension of the springm.

P is an arm attached to the top of the rakehead, and extending forward, and having a downward extension, 19, on its front end. 0 0' are two links, forming a toggle for throwing the lifting-bar into and out of gear with the ratchet-wheels. O is a chain attached to the knee of the toggle and to the seat-standard, and upon which the driver places his foot when agran -gen V he desires to dump the rake. The resultant pull on the chain draws the knee of the toggle forward to the position indicated by the dotted lines, Fig. 2. thus depressing the front end of arm M and throwing the lifting-bar K into gear with the ratchet-wheels, the liftingbar being depressed through the medium of rockbarlland spring-rodsL L. In this positionany further forward motion of the toggle-knee is prevented by the link 0 strikingthedownward projection p of the arm 1, and as the knee is forward of a straight line, joining the extremiticsof the toggle, it will be held in this position byany upward tendency of arm I, whether due to spring in or to the lifting-bar acting through spring-rods I. L.

Q is a screw in the middle beam, ll, against which the knee of the toggle strikes as the rake-head moves forward in the act of dumping, and which thus serves as an adjustable tripping device, the point to which the teeth are raised being regulated by screwing Q farther in or out. The knee of the toggle is thus forced back,and the end of arm M raised and the bar K lifted out of gear with the ratchet wheels by a positive force. lt is therefore impossible that the device should fail to trip at the proper point.

R is an arm on the rake-head for attacle ment of a device for holding the raketeeth down to their work. S is a link eonneeting arm R with the pressure-lever T. The lever 'l is pivoted at 1!, and has a short arm and foot-rest, U, upon which the driver plat-es his foot while riding on the seat, and thus holds the rake-teeth down.

t is a handextension to lever T, by which the rake may be dumped by hand.

The weight of the raketeeth, &e., is supported by lever T pressing again t the edge of beam B.

V, Fig. Land in dotted lines, Fig. Lare two guards for the ratchet-wheels. one for each Wheel, supported by the middle beam, ll,and by the beam I).

In operation, the rake will be dumped by power from both wheels when moving forward in astraight line, and by the powerot' the outside wheel when moving on a curve. In the latter case one end of the lifting-bar will remain down in gear with its ratehetavheel,and the other end will rise over the teeth of its ratchet-wheel, as shown in Fig. 1. This it will be permitted to do by the elastieityot the spring-rod IA. Should the machine be backed while the lifting devices are in gear both ends of the bar will rise over the teeth of the wheels.
